Avarsity cross-country team runs on a course that makes a right turn after 3 miles, and continues on one mile less than the junior varsity team's course. the junior varsity team's course runs on a straight line from the same starting point and the finish line. how long is the junior varsity team's course?

hint: use the pythagorean theorem.

7 miles
5 miles
3 miles

5 miles

Step-by-step explanation:

We are given that A varsity cross-country team runs on a course that makes a right turn after 3 miles, and continues on one mile less than the junior varsity team's course.

The junior varsity team's course runs on a straight line from the same starting point and the finish line.

Refer the attached figure

Let the junior runs course x miles i.e. AC = x

Senior runs 3 miles i.e. BC = 3 miles

Senior  continues on one mile less than the junior ie. AB = x-1

Since ΔABC is a right angles triangle

So,

Thus the junior varsity team's course is 5 miles long.
